You know that the number of protons in an atom determines what element you have. Hydrogen is a common element on earth. Isotopes are atoms of an element with the normal number of protons and electrons, but different numbers of neutrons. Such atoms are called isotopes of each other. Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. (True / False)? Isotopes, by definition, are two atoms with the same number of protons and electrons, but a different number of neutrons. The number of neutrons determines the isotope of an element 13) Hydrogen atoms and Helium atoms both have two protons in their atomic centers, but different numbers of neutrons. Hydrogen is a common element on earth. These have a different number of neutrons, but are otherwise the same. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. The isotopes of an element have different masses because of their different numbers of neutrons. Atoms are made of protons, neutrons, and electrons. The atoms in a particular element have an identical number of protons and electrons but can have varying numbers of neutrons. 14) Hydrogen and Deuterium atoms both have the same number of protons in their atomic centers, but different numbers of neutrons. Hydrogen’s atomic number is 1 — its nucleus contains […] Atoms in a chemical element that have different numbers of neutrons than protons and electrons are called isotopes. Atoms of the same element always have the same number of protons ( is it had a different number of protons it would be a different element). Atoms that have the same atomic number, but different mass numbers are called isotopes. Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Atoms that have the same atomic number but different atomic masses are called isotopes. Atomic mass or mass number is defined as the total number of protons and neutrons that reside in the nucleus of an atom. (True / False)? A neutral atom has the same number of protons and electrons (charges cancel each other out). Whenever we see an element symbol followed by a dash and a number, that number represents the mass of the element. Choice 1 is incorrect since H and He are different elements and therefore have different numbers of protons. Different neutrons are possible. These have the same number of protons but the number of neutrons is different. The identity of an element is determined by … Atoms with the same number of protons and different numbers of neutrons are called isotopes. Protons have a positive charge. If they have different neutrons they are just variations of the same substance For example, the carbon-12 isotope has 6 protons and 6 neutrons, while the carbon-14 isotope has 6 protons and 8 neutrons. For instance hydrogen has one proton, carbon has six. The difference in the number of protons and neutrons in atoms account for many of the different properties of elements. But, all atoms are not the same. Atoms of the same element that have the same number of protons but a different number of neutrons are called isotopes. Having excess neutrons may make isotopes radioactive. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. The charge on the proton and electron are exactly the same size but opposite.
